Class 3 Outbreak is an RTS zombie game running on Google Maps.

Struggle to keep the zombie infection at bay with a hopelessly outnumbered police force, squash any outbreaks that appear and keep the zombie threat level at Class 1 for as long as possible. Protect thousands of civilians over a 1km square area in Washington DC, USA or Leicester, England. Keep an eye out for infected civilians, and make sure none find their way outside of your police unit's reach.
